Safety

Information for the user

In all applications involving the use of machine tools or

CMMs, eye protection is recommended.

Remove power before performing any maintenance

operations.

It is the machine supplier’s responsibility to ensure

that the user is made aware of any hazards involved

in operation, including those mentioned in Renishaw

product documentation, and to ensure that adequate

guards and safety interlocks are provided.

Under certain circumstances the probe signal may falsely

indicate a probe-seated condition. Do not rely on probe

signals to stop machine movement.

The expected method of providing an emergency stop for

Renishaw products is to remove power.

Information for the machine supplier/installer

The automatic probe cover (APC) system must be

installed by a competent person, observing relevant

safety precautions. Before starting work, ensure that

the machine tool is in a safe condition with the power

switched OFF and the power supply to the HSI or HSI-C

disconnected.

vi Before you begin (continued)

Warnings

The following residual risks of this device need to be

managed to an acceptable level by the integrator:

• Sound pressure level: this device emits noise as

an essential part of its operation and has been

measured at 76 dB(A).

• Pinch point: when this device operates there is a

pinching hazard between the stylus cube and the

cover

• Care must be taken when installing or cleaning the

product inside the machine tool to ensure sharp

objects are avoided.

• Ejection of debris: when “air bleed” is activated

debris (including metal particles) can be ejected from

the cover

• Installation of this pneumatically powered device

presents foreseeable pneumatic and mechanical

hazards so should only be installed by a competent

person.

• The sound pressure level, pinch point and “air bleed”

hazards identified above will need to be managed

during maintenance of the machine or this device.

Introduction

The automatic probe cover (APC) is a tool setting

probe that features a pneumatically-operated

protection cover for lathes and multi-tasking

machines. The APC is designed to protect

the stylus when it is mounted in a hazardous

environment on a machine tool.

The APC is typically used when the probe is

mounted in a harsh environment; for example,

where exposed to large pieces of flying swarf, or

long strands of swarf wrapping around the stylus

that can damage the probe when pulled away.

The pneumatically-operated cover will protect

the probe’s stylus and allow it to operate in this

hazardous environment.

2 APC system (continued)

APC probe family

The APC family of tool setting probes currently

consists of:

• APCA air extension and air retraction

• APCS air extension and spring retraction

The term APC used throughout this installation

and user’s guide refers to both versions.

Features

The APC features an “air bleed” function. “Air

bleed” is where air flows through the APC

mechanism at a constant rate over the stylus cube

when the APC cover is extended or retracted to

help prevent build up of contamination on the

stylus cube.

The APC also features an air blast port.

The customer can supply, fit and control an air

blast pipe to suit their requirements. For example

this could be used for cleaning the stylus or

cutting tool before measuring.

NOTE: A retract confirm sensor provides the machine controller with a signal to indicate that the APC cover is retracted.

3Interface unit

HSI interface unit HSI-C interface unit

Introduction

An HSI or HSI-C interface unit is required to

convert the signals from the APC unit into

voltage-free solid-state relay (SSR) outputs for

transmission to the CNC machine controller, which

responds to the probe inputs.

WARNING: Before installing the interface unit,

ensure that the machine is safe to work on. Switch

off machine power when working in the control

cabinet.

In addition to the features of the HSI, the HSI-C

enables the user to select a suitable level of

immunity to false triggering (caused by machine

vibrations or accelerations) for the connected

APC unit. The HSI-C can also respond to a

configuration override input that switches the

probe to the highest level of immunity to false

triggering when manoeuvring to a measure

position at high speed.

4

The interface unit should be installed in the CNC controller cabinet. Where possible, locate the unit away from potential sources of interference such as transformers and motor controllers.

Installing the interface unit

Install and configure the interface unit as

described in the HSI hard-wired system

interface installation guide (Renishaw part no.

H-5500-8554), or the HSI-C hard-wired system

interface – configurable installation guide

(Renishaw part no. H-6527-8501).

13Pneumatic set-up

Introduction

The APC is a pneumatically operated probe cover

that is available in two main configurations:

• APCA where pressure is required for both extending and retracting the cover.

• APCS where pressure is required for extending the cover and an internal spring retracts the cover.

“Air bleed” configuration

Both APCA and APCS can be configured to

provide an “air bleed” function. “Air bleed” is where

air flows at a constant rate over the stylus cube

when the APC cover is extended or retracted to

help prevent build-up of contamination on the

stylus cube and within the mechanism.

“Air bleed” is recommended when the cover is

extended and the machine tool is cutting.

It is also recommended to activate “air bleed”

momentarily when the cover is retracted prior to

measurement.

A flow control valve can be fitted to regulate the

“air bleed”.

NOTES:

“Air bleed” is not guaranteed to remove all debris.

This is dependent on the application and the

environment.

“Air bleed” is created when a pressure limited seal

is activated by the control circuit. This will occur

when pressure is applied to Port 1 when the cover

is fully retracted, or when pressure is applied to

Port 1 when the cover is extended and held with a

pressure greater than 4.5 bar (65.3 psi) on Port 3.

Safe to access the probe (cover retracted)This is confirmed by the retract confirm sensor.

Monitor while measuring.

Mechanical protection

To protect the probe and APC mechanics it is

necessary to restrict the extension speed of the

cover to a minimum of 1 second. A directional

speed control valve should be used that restricts

the extend time but does not restrict the retract

time.

NOTE: It is recommended that the extend operation is completed before “air bleed” is activated.

Air blast stalk

An independently fed DIN EN ISO 228–G 1/8

outlet for an “air blast stalk” is provided for

customer implementation.

This can be used to blow air over the stylus cube

or the cutting tool being measured when the APC

cover is retracted during the measuring cycle.

NOTE: Air blast stalk not provided by Renishaw.

Best practices – pneumatics

WARNING: Before installing the pneumatics, ensure that the machine is safe to work on by

isolating the air supply.

NOTE: Valve Kv (Cv) flow coefficient, pipe length and pipe diameter will affect operating performance. Exhaust lines from valves must be routed to a clean isolated area away from any electrical connections. An exhaust silencer/filter is recommended.

For air supply see “Pneumatic supply” in

specification on page 5.

• Where possible, tap into the air supply that exits the machine air supply filter/regulator unit. Do not connect the APC to an oiled air supply.

• Before connecting the air pipe to the inlet of the APC unit, briefly switch on the air supply to clear out any debris from the pipe. When no more debris is emitted, switch off the air supply and connect to the APC.

• When installing the air pipe supply to the APC, keep runs as short as possible to minimise pressure drop.

• If the temperature of the air supply is greater than +5 °C (+41 °F) above ambient and is humid, an air dryer will be required.

Ø4.0 mm (0.16 in) air pipes to the connectors on

the back of the unit (see “Installation” diagram on

page 23).

Both pneumatic connectors on the APCS (Port 1

and 3) must be connected with pipe. For APCS

with no “air bleed” Port 1 must be connected to an

exhaust/breather line routed to a clean isolated

area away from any electrical connections. An

exhaust silencer/filter is recommended.

Electrical connection

Connect the M12 connector to the mating

cable (not supplied). For more information see

“Connecting the APC to an HSI interface and the

CNC” on page 10 or “Connecting the APC to an

HSI-C interface and the CNC” on page 11 and

“Retract confirm sensor” on page 12.

Mounting the APC to the machine

1. Mount the APC to fitting location using

4 × M4 screws (supplied). Leave the screws

semi-tight.

2. Set the APC base perpendicular to the

mounting face. The gap will be approximately

1 mm (0.04 in). Torque all four screws to

between 2.60 Nm and 2.70 Nm (1.92 lbf.ft

and 1.99 lbf.ft).

26 Installation (continued)

Fitting the stylus

1. Ensure the APC Cover is retracted.

2. Unscrew by hand, and remove the APC

nose cone so the stylus mounting position is

accessible.

Nose cone

0.65 Nm to 0.70 Nm (0.48 lbf.ft to 0.52 lbf.ft)

1.5 mm A/F

3. Fully insert the stylus in place and rotate so

the side face is approximately parallel to the

machine datums.

4. Secure with 2 × M3 grub screws (supplied)

and torque to between 0.65 Nm and 0.70 Nm

(0.48 lbf ft. and 0.52 lbf ft.). For more

information see “Adjusting stylus to align with

machine axis” on page 27.

27Stylus alignment

Adjusting stylus to align with machine axis

1. Check angular misalignment across the

front face of the cube in both X and Y (top

to bottom and side-to-side) relative to the

machine datum. The recommended target is

±10 μm (393.70 μin) across any side face.

2. Adjust the alignment, starting with the axis

with greatest angular error.

As shown below, the adjusting screws are

used to align the axes and secure the APC

into position.

Verify the alignment. Repeat the process until

the desired alignment is achieved.

IMPORTANT: Tighten all adjusting screws

to between 2.60 Nm and 2.70 Nm (1.92 lbf.ft

and 1.99 lbf.ft) when checking alignment and

to secure the APC into position.

3. When the stylus has been adjusted to the

desired setting, check that all four adjusting

screws are torque tightened to between

2.60 Nm and 2.70 Nm (1.92 lbf.ft and

1.99 lbf.ft).

4. Check the rotational alignment of the stylus

cube. Recommended target is ±10 μm

(393.70 μin) across any side face.

5. Align by loosening the 2 × M3 grub screws

shown in diagram below and rotate the stylus

by the amount of error. Retighten the grub

screws to between 0.65 Nm and 0.70 Nm

(0.48 lbf.ft and 0.52 lbf.ft).

6. Check perpendicularity and repeat until

desired setting is achieved.

7. Fit the nose cone and hand tighten until fully

secure.

Operating procedure

30 Service and maintenance

Service

You may undertake the maintenance routines

described in these instructions.

Equipment requiring repair, overhaul or attention

under warranty should be returned to your

supplier.

Maintenance

WARNING: Compressed air can cause physical

injuries.

CAUTION: The APC is a precision tool and must

be handled with care.

NOTE: Ensure the APC is firmly secured to its mounting. Build-up of swarf on or around the APC will be detrimental to its operation.

The APC requires minimal maintenance as it is

designed to operate as a permanent fixture on

CNC machine tools, where it is subject to a hot

chip and coolant environment. Service interval will

depend on operating environment and must be

adjusted accordingly; see “Cleaning instructions”

on page 31.

31Service and maintenance (continued)

Cleaning instructions

WARNING: Before working on the APC, ensure

that it is safe to work on and unable to operate.

Remove any swarf build-up on or around APC

daily (as a minimum, it is recommended to clean

out any swarf build-up in the APC once per week).

1. Fully retract APC cover.

2. Unscrew by hand, and remove the APC nose

cone.

3. Clean the inside of the APC and the nose

cone to remove all the residue swarf or other

debris.

Refer to the diagram opposite and use a soft

brush and low pressure coolant jet.

CAUTION: Do not use compressed air, a sharp tool or a degreasing agent.

4. Fit the nose cone and hand tighten until fully

secure and return to service.

32 Fault-finding

Symptom Cause Action
